Tire Pressure Warning on 2013 Toyota Corolla

Hello:
This morning when I put a key on 2013 Toyota Corolla, there is 'Pressure Warning Light' at the left side of Panel of the car. I drove few blocks, however the warning light does not go away and still there.
My adult son is quite handy in regard to fixing minor problems of the car.
He can rotate all the tires, install the battery and change oil, etc.

Or, is it serious enough to bring it the shop?
Thanks for any help on this problem.

 

Cold temperature causes the tire pressure to go down and can trigger the TPMS. Adding air to the low tire(s) should cause the light to go off either immediately or after a couple of miles of driving. Usually my spare tire in the trunk is the one that causes the TPMS to come on when the seasonal change to cold weather occurs.

If the pressures are OK and the light is still on then one or more of the sensors may need service--possibly a new battery. The service station I go to has a device that can identify which tire is sending the signal and battery levels.

 

would start by checking and filling tire pressure if needed as temps drop so does the air pressure in your tires so you may have one or more to low.

 

Assuming the tires are inflated the TPMS sensor in the tire probably have a dead battery.

They last around 10 years.

 

The tire light comes on my jeep every winter when pressures decrease slightly because of cold temps. As noted above raising the air to the proper psi [or higher] will make the light go out in short order.

My 2010 jeep still has the original valve stem batteries and they work fine ....... knock on wood

 

1. step 1. check pressure with gauge (few bucks any parts store or walmart)
2. pump the tires all same pressure
3. if one tire is low, remove and check for air leaks. If offending leak is found, patch with tire patch (total around $25 for patch kit any parts store or same walmart)
4. if no leaks found, you have bad TPMS battery. Go to Discount Tire, they will check and replace. Replace all four, when one fails, the rest follows. No need to keep chasing them. For Rolla, likely around $80 -100 for all 4 TMPS.

 

Assuming tires need to be dismounted in order to access/replace TPMS. True?

 

Yes

 

Have you actually checked the tire pressure with a gauge on all 4 tires? Because one must be lower than the others. Add air, and the light will go off.

 

Don't forget the spare if you have one.

 

Actually, Discount Tire here replaced TPMs on my Camry in 20 minutes without dismounting tires. Guy did it outside with hydraulic jack and whatever. I saw him through the shop window.

 

You don't have to dismount the tires but you have to break the bead of the tire against the rim. I guess if you want to use tools that pry against the rim, which can scratch, it can be done. If you want to use some 2x4's and do it yourself here is a crazy video.

Personally I've had them replaced with a tire machine and save scratching up the wheels!

 

While I can't say for sure it may be they just replaced the guts of your tire valve. If the tire is broke loose from the rim it would need to be rebalanced.
